Short PDF, 26.4 KB, named 2pg301 and placed in the schematic category alongside related 2pg files. The name gives a part-style code without any device, brand or revision detail, so it is best treated as a compact component reference rather than a board diagram. Technicians typically use such a sheet to read the pinout and limits of a part before testing it in circuit or choosing a replacement. It opens in any PDF reader; confirm the component marking and package on the PCB before relying on the information.
